IMPROVEMENT IN PACKAGES FOR CAUSTIC ALKALIES, ACIDS, AND SALTS.

Specification forming part of Letters Patent No. 123,544, dated FebruaryG, 1872.

Be it known that I, JAooB H. SELBERT, of the city and county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Packages for Caustic Alkali, Acids, and Salts, ofwhich the following is a specification:

My invention consists ina package for putting up caustic or otheralkalies, acids, or salts, made from plaster Paris, or other materialcapable of withstanding the action of said chemicals, the plaster Parisor equivalent material being cast or molded upon a protecting medium insuch a manner as to form a package of the desired form or shape whichwill be cheap, light, and easily constructed, and that will possess allrequisite firmness and strength, capable of protecting its contentsagainst mechanical injury in handling and transportation, and alsoagainst the influence of moisture and external air. Another essentialfeature of my invention is to form the package by casting or molding it,and so uniting the heads with the body that the same will behermetically sealed, and form, as it were, a solid homogeneous mass forcontaining the caustic or other alkalies, acids, or salts such ascaustic soda, blue and white vitriol, potash, condensed lye, Sta-so asto produce packages of any uniform size and weight, for sale in themarket and for safe transportation, the protecting medium retaining thealkalies, acid, or acids in a j pure state, and, in fact, enhance suchchemicals in value. Another important feature of my invention is toarrange one or more disks or partition-plates, made of any desiredmaterial and covered with a protecting compound, within the packages asthe same are being lilled with chemicals, so that each compartmentproduced will be of uniform or graduated capacity,

so that when one compartment is opened it` will not disturb or injurethe adjoining or next one.

In the drawing, Figure l represents a vertical central section oil theimproved package for caustic and other alkalies, acids, and salts. Fig.2 is a section ofthe body of the package as formed on the mold. Fig. 3is a similar section of said body with the bottom inserted therein. Fig.4 is a similar section of the package when complete.

Similar letters of reference indicate corresponding parts in the severalgures. j

In forming the body of the package I employ calcined plaster of Paris,v,or any other equivalent substance, and add thereto about onetenth partof ilour (preferably rye iiour) or mari ble-dust, or any otherequivalent and wellknown substance that will act and harmonize withcalcined plaster. To these ingredients is applied suflicient water orother liquid substance to render the mass plastic, when all arethoroughly mixed together. The paper, pasteboard, muslin, or otherfabric, E, is wrapped around the bed B to form the chamber l), one ormore sheets being used, and, if desired, arranged so as to break joints.The plastic mass I cast in thel space or chamber D, so that the samewill adhere to the protecting medium and form a solid compact body, asin Fig. l. After the plastic mass has set or indurated I lwithdraw themold A and remove the cylinder or roll H from the bed B, the packagebeing left formed, as shown in Fig. 2. Vhen the package is thus formedit is ready to receive the bottom G, which I prefer to combine with thebody by dipping the same into a plastic mass, of the required depth,composed of a compound same as that of which the body is formed, so thatthe two will unite and be hermetically sealed. v

Instead of dipping the cylinder into a plasf tic mass, I can and intendto form the bottom by placing the said cylinder upon a stand or tray,and pour plastic material down into the cylinder so that it will combinewith and form the bottom of the cylinder, leaving no joint, but beinghermetically sealed, so as to eii'ect absolute exclusion of air ormoisture.

When the package is thus produced, as in Fig. 3, I coat its interiorsurface with one or more layers composed of a solution of rosin,sealing-wax, or other suitable material best adapted for the purpose.`The package is now charged with the caustic or other alkali, acid,salt, or other chemicals to be packed, where a previously-prepared orcoated disk or plate, of any material, is placed upon the contentsleaving a short space between said disk and the top of the cylinder,into which space is cast the head G', the compound employed being thesame as that composing the cylinder. The head is thus combined with,and, in fact, adheres to the inner surface of the cylinder, so as `toform a homogeneous part of the same, leaving' no perceptible joint.

When packages containing alkalies, acids, or

salts are once opened the condensed alkalies, Ste., deliquesce, andunless all is immediately used it is rendered useless. To overcome thisdefect in such packages I arrange disks or partitions I I within thechamber or cavity of the package as the same are being filled withchemicals, the disks or partitions being iirst coated with rosin andsealing-wax, or other suitable protecting medium. By this meanscompartments are formed in the packages, so that when one compartment isopened to get access to the chemicals contained therein it can be'usedwithout disturbing'or injuring the next adjacent one, which allows theconsumer to use any given quantity, as each compartment can be graduatedin capacity. Y

By these means a package is produced which protects the alkali or othermaterial against injury from the iniiuence of moisture of theatmosphere, and also against all danger from being spilled or lost bycareless handling, in the transportation, or otherwise; and at the sametime my package can be made cheap and with great facility.

I do not confine myself to calcined plaster of Paris and our, or to anydefinite proportions, for I intend to employ any powdered substance thatcan be reduced to a plastic state for casting or molding the carrier orbody, and

combining it with -paper or other fabric as a protecting medium.

Having thus described my invention, what I` claim as new, and desire tosecure by Letters Patent, is

1. A package for alkalies, acids, salts, or other chemicals, made of aplastic compound by casting the same in a protecting wrapper of paper orother suitable material, for the purpose set forth.

2. Also the within-described process of forming packages for alkalies orother chemicals by means of a mold, A, a protecting-wrapper, E, and abed, B, substantially in the manner speeied. Y.

3. Casting in the heads of packages for containing alkalies, acids, orsalts, so that the said heads will combine with the package and form asolid mass, leaving no joint, as set forth.

4. Partitions I I arranged' within packages for putting up alkalies,acids, or salts, for the purpose of forming compartments, for thepurpose specified. l

To the above I have signed my name this 24th day of January, 1872.
